Ibisobanuro birambuye kubiranga n'inzira ya hydrophilique idoda

Polypropilene (PP) idoda idoda ikoreshwa cyane kubera imikorere yayo myiza, uburyo bworoshye bwo gutunganya, nigiciro gito. Cyane cyane mu myaka yashize, yakoreshejwe cyane mubice nkubuvuzi, imyambaro, ibikoresho byo gupakira, ibikoresho byohanagura, ibikoresho bitwikiriye ubuhinzi, geotextile, ibikoresho byo kuyungurura inganda, nibindi, kandi bifite gahunda yo gusimbuza ibikoresho gakondo.

Bitewe nuburyo butari inkingi ya PP, mubusanzwe butarimo amatsinda ya hydrophilique, PP idoda idoda mubusanzwe nta mikorere yo kwinjiza amazi. Guhindura Hydrophilique cyangwa kurangiza birakenewe mugukora hydrophilique PP idoda.

I. Uburyo bwo gutegura imyenda ya hydrophilique idoda

Kugirango tunoze hydrophilicity yimyenda ya PP idoda, mubisanzwe hariho uburyo bubiri bwo kunoza ubuso bwabo: guhindura umubiri no guhindura imiti.

Guhindura imiti ihindura cyane cyane imiterere ya PP kandi ikongeramo amatsinda ya hydrophilique muminyururu ya macromolecular, bityo igahindura hygroscopique. Hariho uburyo cyane nka copolymerisation, gushushanya, guhuza, hamwe na chlorine.

Guhindura kumubiri bihindura cyane cyane imiterere yo hejuru ya molekile kugirango itezimbere hydrophilique, cyane cyane binyuze mu guhuza (mbere yo kuzunguruka) no guhindura ubuso (nyuma yo kuzunguruka).

II. Guhindura bivanze (kuzunguruka mbere yo guhindura)

Ukurikije ibihe bitandukanye byongeweho byongeweho byongeweho, birashobora kugabanywa muburyo bwa masterbatch, uburyo bwuzuye bwa granulation, hamwe nuburyo bwo gutera inshinge.

(1) Uburyo busanzwe bwamabara

Ubu ni uburyo bwingenzi bwo gukora hydrophilique idoda imyenda idakozwe nabakora imyenda idoda.

Ubwa mbere, inyongera ya hydrophilique isanzwe ikorwa mubice bya jellyfish nabakora ibiti, hanyuma bikavangwa na PP kuzunguruka kugirango babe umwenda.

Ibyiza: Umusaruro woroshye, ntukeneye kongeramo ibikoresho ibyo aribyo byose, bikwiranye n’umusaruro muto w’inka, wongeyeho imbaraga za hydrophilique.

Ibibi: Buhoro buhoro hydrophilicité no gukora nabi gutunganya, akenshi bikoreshwa mubudodo. Igiciro kinini, inshuro 2 kugeza kuri 3 kurenza guhinduka hejuru.

Guhindagurika nabi bisaba guhindura inzira. Abakiriya bamwe bapfushije toni 5 yimyenda munganda ebyiri zibara amabara badatanga ibicuruzwa byarangiye.

(2) Uburyo bwuzuye bwo guhunika

Kuvanga modifier, uduce twa PP, hamwe ninyongeramusaruro zingana, ubisekure munsi yumugozi kugirango ubyare hydrophilique PP, hanyuma ushonge hanyuma ubizunguze mubitambaro.

Ibyiza: Gutunganya neza, ingaruka zirambye, nigitambara gishobora gukoreshwa.

Ibibi: Harakenewe ibikoresho byongeweho ibikoresho bya screw, bivamo igiciro kinini kuri toni na hydrophilicity gahoro, bigatuma bikenerwa gusa n’umusaruro munini.

(3) Gutera Fangqian

Ongeraho mu buryo butaziguye reagent ya hydrophilique, ni ukuvuga polymer hydrophilique, kumurongo wingenzi wimyenda idoda hanyuma ubivange na PP gushonga kugirango bizunguruke.

Ibyiza: Ingaruka ni ndende kandi umwenda urashobora kongera gukoreshwa.

Ibibi: Bitewe no kudashobora kuvanga neza, kuzunguruka akenshi biragoye kandi bikabura kugenda.

III. Ubuso bwa hydrophilique burangije (nyuma yo kuvura)

Kurangiza Hydrophilique nuburyo bworoshye, bukora neza, kandi buhendutse bwo gukora hydrophilique idoda. Benshi mubadukora imyenda idoda cyane bakoresha ubu buryo. Inzira nyamukuru niyi ikurikira:

Kurubuga rwa spunbond rushyushye ruzengurutse imyenda idoda - gutwikisha uruziga cyangwa gutera amazi ya hydrophilique - infragre cyangwa umuyaga ushushe

Ibyiza: Nta kibazo cyizunguruka, ingaruka za hydrophilique yihuse yimyenda idoda, gukora neza, igiciro gito, ni 1 / 2-1 / 3 byigiciro cyibisanzwe bisanzwe. Birakwiye kubyara umusaruro munini;

Ibibi: Bisaba kugura ibikoresho bitandukanye nyuma yo gutunganya, bihenze. Nyuma yo gukaraba inshuro eshatu, igihe cyo kwinjira mumazi cyiyongera inshuro 15. Ntushobora kuzuza ibisabwa kugirango ukoreshwe;

Umusaruro rusange;

Ibyiza n'ibibi by'ubu buryo bigena ko bikoreshwa cyane cyane ku bicuruzwa bikoreshwa bisaba kwinjizwa cyane na hydrophilique, nk'ibikoresho by'isuku, impuzu, ibitambaro by'isuku, n'ibindi.

Ⅳ.Gukoresha Hydrophilique Igizwe na PPS03 Uburyo

Urebye ibyiza nibibi byuburyo (-) na (ii), uburyo bwa hydrophilique nyina wa hydrophilique PPS030 bwakozwe

Ubu bwoko bwa jellyfish bugira ibiranga dosiye yo hagati (isa nuduce dusanzwe twa jellyfish), ingaruka yihuse, ingaruka zo gukwirakwira vuba, ingaruka nziza, ingaruka zimara igihe kirekire, kwihanganira gukaraba neza, ariko igiciro gito cyane (bisa nuduce duto twa jellyfish).

Kuzunguruka neza, nta mpamvu yo guhindura imikorere.

Birakwiriye kubyara umusaruro muto hamwe no gukaraba cyane, ibicuruzwa byongera gukoreshwa nkamashyamba nigitambara cyubuhinzi.

Ibipimo nyamukuru byerekana isuzuma rya hydrophilique PP idoda idoda harimo kwinjiza amazi, inguni yo guhura, ningaruka za capillary.

. Iyo amazi menshi yinjiye, niko ingaruka nziza.

. Nyuma yo gushonga, kura isahani yikirahure hanyuma ukonje mubisanzwe ubushyuhe bwicyumba. Gupima uburinganire buringaniye ukoresheje uburyo bwo gupima. Gutoya guhuza impande, nibyiza. (PP idoda idoda idafite hydrophilique nyuma yo kugera kuri 148 ° C).
